select Date,TotalAllowance 
from Calculation 
where EmployeeId=1
  and convert(varchar(10),Date,111) between '2011/02/25' and '2011/02/27'

这对我很有效

SELECT 
  * 
FROM 
  `request_logs` 
WHERE 
  created_at >= "2022-11-30 00:00:00" 
  AND created_at <= "2022-11-30 20:04:50" 
ORDER BY 
  `request_logs`.`id` DESC

我们可以使用between来显示两个日期数据，但这将搜索整个数据并进行比较，因此对于巨大的数据，它会使我们的过程变慢，所以我建议每个人都使用datediff:

qry = "SELECT * FROM [calender] WHERE datediff(day,'" & dt & "',[date])>=0 and datediff(day,'" & dt2 & "',[date])<=0 "

这里的日历是表，dt作为开始日期变量，dt2是结束日期变量。

select Date,TotalAllowance 
from Calculation 
where EmployeeId=1
  and convert(varchar(10),Date,111) between '2011/02/25' and '2011/02/27'

试试这个:

select Date,TotalAllowance from Calculation where EmployeeId=1
             and [Date] between '2011/02/25' and '2011/02/27'

日期值需要作为字符串输入。

为了确保您的SQL Server 2008及更高版本的查询能够适应未来，Date应该被转义，因为在以后的版本中它是一个保留字。

请记住，没有时间的日期将午夜作为默认值，因此这里可能没有正确的值。
